To define these terms used in describing muscle physiology: multiple motor unit summation‚ maximal stimulus‚ treppe‚ wave summation‚ and tetanus. 2. To identify two ways that the mode of stimulation can affect muscle force production. 3. To plot a graph relating stimulus strength and twitch force to illustrate graded muscle response. 4. To explain how slow‚ smooth‚ sustained contraction is possible in a skeletal muscle. 5. To

What are the observations that you have made? (maximum 150 words) The experiment was carried out by using the amplitudes as low as 0.00mA to locate the twitching. But volunteer was not able to feel any twitch response from the amplitude of 0.00mA to 6.5mA. But to be close to accurate we located the twitch

he hops from chair to chair‚ swinging his arms and legs restlessly‚ and then begins to fiddle with the light switches‚ turning the lights on and off again to everyone ’s annoyance--all the while talking nonstop. When his teacher encourages him to join a group of other children busy in the playroom‚ Danny interrupts a game that was already in progress and takes over‚ causing the other children to complain of his bossiness and drift away to other activities. Even when Danny has the toys to himself

Beginning 1993/94 it was carried out at an interval of five years and the recent survey was undertaken in 2009/2010. The survey covered private households in urban and rural areas. The main objective of HES was to collect information on the level and pattern of consumption expenditure by households on a comprehensive range of goods

Depending on the geographic location of the installation‚ galvalume has approximately nine times the longevity of galvanized steel. Zinc GuttersZinc gutters are usually made from an alloy of 99.5 percent zinc with small amounts of copper and titanium. Similar to copper‚ zinc is normally used unpainted and will develop a protective patina that

LABORATORY REPORT Activity 2: Twitch Contractions and Summation PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: contraction force increases‚ becoming maximum at an optimal length‚ then decreasing at longer lengths. Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases‚ the force of contraction: increases. MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable: contraction force
